GEORGE IV. CROZIER, OF MUNCIE, INDIANA.

GAS-PRESSURE REGULATOR.

SPECIFICATION forming part of Letters Patent No. 408,873, dated August 13, 1889.

Application filed March 27, 1889.

To all whom it may concern:

Be it known that I, GEORGE W. ORozIER, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Gas-Pressure Regulators, of which the following is a description.

My invention relates to a device for regulatin g the pressure of gas, the object being to provide a gas-regulator which will insure a uniform pressure in the supply.

The invention consists in the features of construction and combinations of parts hereinafter fully described, and pointed outin the claims.

In the drawings, Figure 1 is a perspective view of my improved regulator with a part broken away. Fig. 2 shows the valve-rod and elastic disks removed from the gas-chamber. Fig. 3 is a vertical central section, and Fig. at is a detail of a part of my said invention.

A represents the chamber, consisting of a ring or casing a and counterpart caps or covers a a. The latter have lugs formed with openings, and projecting beyond the ring a to receive securing-bolts I), held by nuts Z). The two elastic disks B B are secured one on either side of the ring a by the caps to a, which clamp the edges of the disks against the ring, as clearly shown. in Figs. 1 and 3. The ring a is formed with diametrically-opposite openings 0 and c, which communicate, respectively, with inlet and discharge pipes O and D. The inlet 0 is provided with a valve E, secured to one end of a valve-rod F, the other end of the rod having a sliding bearing in a casting G, secured within the ring a over the discharge D. The discharge-opening is provided with an independent valve and valve-rod H, of any suitable construction.

I I represent flat springs arranged one on either side of the valve F. The ends of these springs nearest the gas-inlet are secured to a nut or square collar J, rigidly secured upon the rod F. The opposite ends of the springs are secured to a block g,.arranged within the casting G.

To the end of the discharge-pipe D is connected a T-coupling D, having a screwthreaded aperture (1 in its outer end, in which is mounted an adjustable screw-threaded rod Serial No. 305,049. (No model.)

D Said rod extends through the discharge pipe into the chamber A, and is pivotallyconnected to the block g. By means of this adj ustable red the block g may be adjusted to or from the center of the chamber, and as it is rigidly connected with the valve-rod through the springs I it will move said valve-rod with it and regulate the play required to close the valve. It will be readily seen that the greater the play of the valve-rod the greater the pressure required to close the valve. By means of the adjustable rod and block above described the play of the valm-rod can be regulated, and thus determine the degree of pressure re quired to close the valve.

Each of the rubber disks is provided centrally with a yoke K, held in place by a screw 7c, nut Z, and an inner and outer washer. The yokes K embrace the springs I I, and are secured thereto by cross-pins i 11.

The operation of the device is as follows: IVhen the supply of gas to the chamber exceeds the desired amount, or, in other words, when .the pressure becomes too great, the rubber disks expand, and their expansion operates to draw the springs I I apart and to close the inlet-valve by the pull upon the valve-rod. As soon as the pressure on the rubber disks is relieved the latter contract, and the inletvalve is thus opened. It will be. apparent that by the means thus described an even pressure of gas is insured to the supply-pipes.

I claim- 1. The combination, with a chamber, of a valve-rod, a pair of springs secured upon the valve-rod, and flexible disks secured to said springs, substantially as set forth.

The combination, with a chamber cons-I sisting of a ring and removable caps, of a valve-rod extending diametrically through the chamber and connected to the supplyvalve, flat springs secured at their ends to said rod, and flexible disks secured to said springs and adapted to control the supply of gas, substantially as set forth.

3. The combination, with the chamber, of. a valve-rod extending through the same, flat springs rigidly secured at their ends to said rod, flexible disks, and devices for securing the latter to said springs, substantially as set forth.

to block located within the chamber, a pair of springs secured at one end to the Valve-rod and at their other ends to the adjustable block, and flexible disks secured within said chamber and connected with the springs attached to the valve-rod, all constructed, arranged, and operating, substantially as shown and described.
